Blizzard Entertainment shocked a lot of people when it revealed Hearthstone: Heroes of Warcraft, a card battle game set within the popular World of Warcraft universe. Coming soon to iPad, PC, and Mac, this highly anticipated effort lets players build decks around nine WoW character classes and compete in cross-platform multiplayer. As expected, the game will include common and rare cards. Not only that, but the studio hopes to experiment with in-app purchasing with the upcoming beta that users are free to sign up for.

“We’ve always loved collectible card games at Blizzard, so it’s been exciting to bring everything we love about the genre to life in Hearthstone,” said Mike Morhaime, CEO and cofounder of Blizzard Entertainment. “We’re putting a lot of focus into creating a fun new game that’s easy to pick up and play, but also has a lot of depth. We can’t wait to share it with everyone."
